Memory Leak Vulnerability in Linux Kernel Coresight Component

CVE-2023-53261

What is CVE-2023-53261?

A memory leak has been identified in the coresight component of the Linux Kernel, specifically linked to the management of ACPI buffers. The leak occurs when the internal pointer used for buffer allocation is not properly freed, leading to unreferenced memory over time. This could result in degraded system performance as resources are unnecessarily consumed. The issue was mitigated by moving variable declarations to ensure that memory is released before exiting the function, thereby preventing the ongoing leakage of allocated memory. Proper handling of ACPI buffers is crucial for maintaining optimal performance.
